Will Garcia

I specialize in architecting highly concurrent, cloud-native backend systems that enable real-time decision-making and complex transactional workflows. My career centers on engineering event-driven architectures with Java and Vert.x, using reactive, non-blocking design to remove performance bottlenecks at scale.

Most recently, I architected a high-throughput, event-driven payment reconciliation platform for a major financial services firm, processing millions of transactions with near-real-time latency and strict consistency guarantees. I engineered the core transactional pipeline with Vert.x, integrated AWS ECS and AWS SQS for resilience, built an internal AI-assisted code review and refactoring tool, and improved average API response times by 40% through PostgreSQL profiling, tuning, and query rewrites.

I also lead platform quality and operational excellence—directing CI/CD pipelines with GitHub Actions and Jenkins, implementing OAuth 2.0 RESTful API gateway security and rate limiting, and delivering monitoring/alerting dashboards with AWS CloudWatch. Earlier, at BMW Group and GE Power, I delivered real-time streaming telemetry and energy management services (Java/Vert.x, Spring Boot, Kinesis, Lambda, Redis), and I continue to mentor engineers in resilient reactive systems while migrating legacy systems toward event-sourced architectures.
